AstroDigi | Friday, 19 Aug 2011 | Of the five species of freshwater dolphins in the world, the Amazon River Dolphin pink, or Boto, are the most intelligent. Dolphins are friendly and have a brain capacity 40% greater than humans.
Since a few years ago, this mammal is one of the most endangered species of swimmers among the dolphins in the world. This is due to the destruction and deforestation of the rainforest (rainforest) in the Amazon region where they live.
Social habits they do not like the bottle-nosed dolphins are most common. They have no predators, except for "man", so they do not need to travel in large groups.
It is unclear what causes the unique color of the Boto, but the presence of cells of capillaries on the surface of their skin may contribute to some or most of the color of their birth. Other factors that also determine the age, and also the temperature of the water where they live.
Scientists who have studied botos ancestors, did not find much information even if they find that the ancestors of Boto has entered the Amazon River through the Pacific Ocean about 15 million years ago.
Boto has two different colors. Pink and gray. "Scientists say that the older dolphins they become more and more pink color. Therefore, if you look at the picture with the mother and baby pink dolphins, you may not believe that the baby gray is the son of the pink dolphins.
Dolphins eat crustaceans (such as crabs, and shrimp, etc.) catfish, and other freshwater fish. They are so flexible necks, allowing them to turn his head to 180 degrees backward. It helps them to move more freely in the area of deep water, water meadows, rivers and shallow waters.
They have a distinct hump on their back with bottle nose dolphins that has fins on its back. Has a similar elongated Pinocchio nose, making their appearance is rather unique look.
The biggest threat these beautiful creatures are fishermen with their nets. Fortunately, all dolphins are able to act aggressively, and instinctively know to stay away, so they're not much caught.
As the animal with the highest intelligence they can distinguish between humans that come with a net that threatens the safety to humans that come with friendship.
Although. . like humans, they may not know the hidden malicious intent within the human mind. And sometimes they are also mistaken instinct. These animals are very friendly and welcoming and also a helper to humans. When playing with humans Boto be very careful until the sharp teeth until they are not harmful to humans (see the video).
Unfortunately until now, there is no test that is open and extends related dengankecerdasan dolphins. Although scientists have found that the ratio of brain mass to body weight compared to their difference in a lot of bottle-nosed dolphins.
Their size varies but they generally can reach 2.5 or 3 meters long, weighing about 90 kilograms. Males are generally larger than females, but sometimes you also can find females with a larger size.
River dolphins reach sexual maturity when they reach 2 meters in size. Their mating season is between July and September. Their gestation period is between 9 and 12 months. Dolphins are still a small river called the "calf". This title just like other dolphins around the world.
Amazon Orinoco region, in South America is the only place in the world, where you can find pink dolphins. These creatures are truly in the list of endangered species and we need to preserve them.
Hopefully this article can readers realize the importance of protecting and preserving the flora and fauna. How about you?
